It is not intended to be limited to the embodiment.

[Example 1]
In the present embodiment, a three-dimensional modeling apparatus in which the peeling assisting unit performs a peeling assisting operation by adjusting the temperature of the contact portion with the stage of the modeled object will be described.
FIG. 1 is a schematic cross-sectional view illustrating an overall configuration of a three-dimensional modeling apparatus 100 that performs lamination by thermal welding in the first embodiment.
The three-dimensional modeling apparatus 100 is an apparatus for modeling (forming) a modeled object 115, and a layer (corresponding layer) corresponding to a cross section obtained by cutting a three-dimensional modeling target object in parallel planes is provided on a stage (supporting unit) 114. By sequentially laminating them, a modeled object 115 that becomes a three-dimensional model of the modeled object is formed.
The three-dimensional modeling apparatus 100 includes an image forming unit 101, a transfer unit 102, a layered modeling unit 103, a control unit 104, and an operation unit 105.

  The image forming unit 101 includes a cartridge (process cartridge) 106 including a photosensitive drum 107, a first transfer belt 108, a transfer roller 109, and a transfer roller 110. The cartridge 106 is detachably attached to the unit main body of the image forming unit 101. The transfer unit 102 includes a second transfer belt 111, a rotation roller 112, a transfer roller 117, and a heater 113. The layered modeling unit 103 has a stage 114. The stage 114 incorporates a heater 116 that performs temperature control to assist the peeling operation. By being heated by the heater 116, the temperature of the surface 114a of the stage 114 (contact portion with the modeled object 115, hereinafter, the stage surface) 114a is controlled. The control unit 104 incorporates a controller having a controller, a user interface, and various I / O interfaces, and controls various controls of the entire apparatus.

  A plurality of cartridges 106 (four types in this embodiment) are provided, and the user inserts each cartridge 106 into the three-dimensional modeling apparatus main body from the front and attaches it. The plurality of cartridges 106 are juxtaposed along the conveying direction of the first transfer belt 108, and each cartridge 106 faces each transfer roller 109 via the first transfer belt 108 above each transfer roller 109. Are arranged to be. The first transfer belt 108 is disposed so as to be sandwiched between the photosensitive drum 107 provided in the cartridge 106 and the transfer roller 109.

Each cartridge 106 stores (accommodates) each modeling material independently. Here, the modeling material is a structural material for configuring the modeled object 115 or a support material (supporting material) for preventing the modeled object from being deformed during modeling.
The modeling material stored in each cartridge 106 is supplied to the photosensitive drum 107. The photosensitive drums 107 corresponding to the modeling materials provided in the cartridges 106 are arranged along the transport direction (the direction of arrow a shown in FIG. 1) during the image forming operation.

Here, an image (laminated cross-sectional image) forming operation performed in the image forming unit 101 will be described.
An image is formed on the photosensitive drum 107 by supplying a modeling material having a particle diameter of 5 to 100 μm to the photosensitive drum 107 exposed by the optical system. The image formed on the photosensitive drum 107 is transferred onto the first transfer belt 108 sandwiched between the photosensitive drum 107 and the transfer roller 109, and an image is formed on the first transfer belt 108.
The image formed on the first transfer belt 108 is conveyed to the transfer roller 110 as the first transfer belt 108 moves.

In the image forming unit 101 and the transfer unit 102, the transfer roller 110 and the transfer roller 117 are disposed to face each other with the first transfer belt 108 and the second transfer belt 111 interposed therebetween. The image formed on the first transfer belt 108 is transferred to the second transfer belt 111 at a contact portion between the first transfer belt 108 and the second transfer belt 111.
The present invention is not limited to the image forming method of the laser type printer described above, and images of various types of printers such as thermal printers (sublimation type, thermal transfer type, etc.), dot impact printers, LED printers, ink jet printers, etc. It is applicable to the forming method.

  In the transfer unit 102, the image transferred onto the second transfer belt 111 is transported in the direction of arrow b shown in FIG. The image on the second transfer belt 111 is heat-welded by the heater 113 to the modeled object 115 formed in the layered modeling unit 103 for each length of a predetermined modeling unit. Here, the length of the predetermined modeling unit varies depending on the size of the modeled object 115 to be modeled. For example, when the size of the cross section of the modeled object 115 is equivalent to the L size photo size, the length in the transport direction is 135 mm, and when the cross section is equivalent to the A4 size, the length in the transport direction is 297 mm. At the first heat welding, the image on the second transfer belt 111 is heat-welded on the stage 114 (stage surface 114a).

In the layered modeling unit 103, the modeled object 115 is modeled on the stage 114 by performing lamination by thermal welding on the stage 114. At the time of heat welding, the stage 114 moves in the d direction in synchronization with the moving operation of the second transfer belt 111. After heat welding, it descends in the e direction according to the thickness of the stack and moves in the f direction. When modeling is completed, the stage 114 moves in the d direction. When the modeling of the different modeling object 115 is started, the stage 114 moves in the c direction. However, directions c to f may be directions other than those illustrated depending on the device configuration.
The operation unit 105 is used to check the modeling status for each order, such as whether the specified ordered model is being modeled or the model has been completed, to check the device status such as the remaining modeling material, and to perform device maintenance such as belt cleaning. This is a unit for the operator to operate / confirm.

FIG. 2 is a block diagram for explaining a control configuration in the three-dimensional modeling apparatus 100 of the present embodiment.
The three-dimensional modeling apparatus 100 receives 3D data from the client (client) terminal 201 and performs modeling.
The control unit 203 receives 3D data from the client terminal 201, generates sheet data, and transmits the generated sheet data to the print engine unit 204. In addition, the control unit 203 determines whether or not the job that confirms whether all the sheet data recorded in the output spooler 210 has been formed by the print engine unit 204, and notifies the print engine unit 204 when the job ends.
The control unit 203 records the received 3D data in the input buffer (input spooler) 205.

The job analysis unit 206 receives 3D data from the input buffer 205, performs analysis processing, and transmits a job analysis result to a layout instruction unit 207 and a UI (user interface) unit 209. Further, the job analysis unit 206 receives a layout instruction end notification from the layout instruction unit 207.
The UI unit 209 receives the job analysis result from the job analysis unit 206 and displays it on the UI.
The layout instruction unit 207 receives the job analysis result from the job analysis unit 206, organizes the layout information, and transmits the job analysis result and the layout instruction to the image processing unit 208. Further, the layout instruction unit 207 receives an image processing end notification from the image processing unit 208. In addition, the layout instruction unit 207 transmits a layout instruction end notification to the job analysis unit 206.

The image processing unit 208 receives the job analysis result and the layout instruction from the layout instruction unit 207, performs image processing, and transmits an image processing end notification to the layout instruction unit 207. In addition, the image processing unit 208 transmits the image processing result to the output spooler 210.
In the image processing unit 208, the error correction unit 215 corrects the received job analysis result as necessary, and transmits the corrected job analysis result and layout information to the slice unit 216.
The slice unit 216 receives the corrected job analysis result and layout information from the error correction unit 215, performs slice processing, and transmits the slice image and layout information to the imposition processing unit 217.

The imposition processing unit 217 receives the slice image and layout information from the slice unit 216, performs layout processing, and transmits sheet data to the output spooler 210.
The output spooler 210 receives sheet data from the image processing unit 208, records the sheet data, and transmits the sheet data to the print engine unit 204.

The print engine unit 204 receives sheet data from the control unit 203 and performs modeling. Further, when notified of the end of the job, the print engine unit 204 instructs the temperature control unit 214 to perform temperature control of the heater 116 for peeling the modeled object 115 from the stage 114. Here, the temperature control unit 214 and the heater 116 correspond to a peeling assist unit.
The print engine unit 204 transmits the received sheet data to the color conversion unit 211. The color conversion unit 211 performs color conversion on the received sheet data as necessary, and transmits the sheet data to the printing unit 212.

The print unit 212 receives sheet data from the color conversion unit 211 and performs modeling. Further, the printing unit 212 receives setting values at the time of modeling and at the time of peeling from the cartridge detection unit 213.
In the present embodiment, this set value includes the following items. It is a heater control method for each of a target temperature and a plurality of temperature zones (temperature ranges). At the time of temperature control, the heater is controlled according to the temperature zone at that time, so that the contact portion of the modeling object 115 with the stage 114 at that time (near the fixed portion of the modeling object 115 with the stage 114) is controlled. The temperature approaches the target temperature.

The cartridge detection unit 213 reads information about the set cartridge 106 when the cartridge 106 is set in the unit main body of the image forming unit 101. The cartridge detection unit 213 identifies the type of the set cartridge 106 (such as the type of modeling material), and sets the setting values for modeling and peeling according to the modeling material of the cartridge 106, and the printing unit 212 and the temperature control unit 214. Send to.
FIG. 4 is a diagram illustrating an example of setting values for modeling and peeling according to the cartridge. FIG.
As shown, the setting value is set in advance for each cartridge, that is, according to the type of modeling material.

The temperature control unit 214 receives setting values for modeling and peeling from the cartridge detection unit 213 and performs temperature adjustment for modeling and peeling based on the received setting values.
In this embodiment, the temperature control unit 214 controls the heater 113 during modeling, and controls the heater 116 during peeling. At this time, the control may be performed based on the detection result of the sensor that detects the temperature of the contact portion of the modeled object 115 with the stage 114 at that time.
In this embodiment, when peeling is performed, the heater 116 is controlled by the temperature control unit 214 as an operation for assisting the peeling operation, and the temperature of the contact portion of the model 115 with the stage 114 is adjusted. Thereby, the contact part with the stage 114 of the molded article 115 can be softened. This makes it easy to peel the modeled object 115 from the stage 114. As described above, since the set value corresponding to the modeling material is transmitted to the temperature control unit 214, the temperature control unit 214 contacts the modeling object stage according to the material of the contact part with the modeling object stage. The temperature of the part can be adjusted to a temperature at which the shaped article is easy to peel off from the stage. For example, when the contact part with the stage of a modeling object is comprised with the material A, the temperature A which is easy to peel the material A from a stage can be made into target temperature, and this contact part can be adjusted to the temperature A. In the case where the contact portion of the modeled object with the stage is made of the material B, the temperature of the contact portion may be adjusted with the temperature B at which the material B is easily peeled from the stage as a target temperature. The target temperature may be determined in consideration of the relationship between the viscoelasticity of the modeling material and the temperature.
In addition, when performing three-dimensional modeling using only one type of three-dimensional modeling apparatus or a modeling material having substantially the same viscoelasticity change due to temperature, each setting value is held in advance by the printing unit 212 and the temperature control unit 214. May be.

FIG. 4 shows an example in which one set value is set in advance for each cartridge. However, for example, when a plurality of heaters are provided, a plurality of values are set for one cartridge so as to correspond to each heater. May be provided (prepared). This will be described below.
FIG. 5 is a diagram illustrating an example of setting values for modeling and peeling according to the cartridge, and FIG. 5 illustrates an example in which a plurality of setting values are provided for one cartridge.
The setting value received from the cartridge detection unit 213 may be a value derived based on the apparatus configuration from a plurality of setting values for modeling and peeling according to the cartridge as shown in FIG. For example, if there are a plurality of modeling heaters 113 so as to derive XXX ′ and XXX ″ in FIG. 5 from XXX in FIG. 4, a setting value corresponding to each heater 113 may be derived. Further, if there are a plurality of peeling heaters 116 so as to derive MMM ′ and MMM ″ in FIG. 5 from the MMM in FIG. 4, a set value corresponding to each heater 116 may be derived. When the set value is derived from the information read from the cartridge based on the device configuration, the set value may be derived by the cartridge detection unit 213, the temperature control unit 214, or a separately provided setting. It may be derived by a value deriving unit.

Next, the processing flow of the control unit 203 will be described with reference to FIG.
FIG. 3 is a flowchart showing a control flow in the three-dimensional modeling apparatus 100 of the present embodiment.
First, in step S301, the cartridge detection unit 213 reads cartridge information, and the temperature control unit 214 receives setting values for modeling and peeling related to the modeling material from the cartridge detection unit 213. Next, in step S302, the control unit 203 receives 3D data from the client terminal 201, and stores the received 3D data in the input buffer 205 in step S303.

  In step S304, first, the job analysis unit 206 analyzes the 3D data read from the input buffer 205, and transmits the job analysis result to the layout instruction unit 207. A layout instruction unit 207 organizes layout information and transmits a job analysis result and a layout instruction to the image processing unit 208. In the image processing unit 208, the error correction unit 215 corrects the job analysis result as necessary, and transmits the corrected job analysis result and layout information to the slice unit 216. Then, the slicing unit 216 performs slicing processing and transmits the slice image and layout information to the imposition processing unit 217. The imposition processing unit 217 performs layout processing from the slice image and layout information, and records sheet data (sliced data after layout processing) in the output spooler 210 in step S305.

In step S306, the control unit 203 estimates the consumption of the modeling material in each cartridge used in the sheet data recorded in the output spooler 210, acquires the remaining amount of each cartridge from the cartridge detection unit 213, and estimates Compare the amount to the remaining amount. If the remaining amount is insufficient with respect to the estimated amount (spool amount), the UI unit 209 is notified of the insufficient remaining amount in step S311. When the modeling material is replenished by replacing the cartridge or the like (step S312), the determination in step S306 is repeated again. If the remaining amount is greater than or equal to the estimated amount in step S306, the process proceeds to step S307.
In step S307, the control unit 203 transmits the sheet data recorded in the output spooler 210 to the print engine unit 204, and performs lamination. At that time, the temperature control unit 214 performs temperature control based on the setting value for modeling related to the modeling material read in step S301.

In step S308, the control unit 203 compares the sheet data recorded in the output spooler with the number of sheets formed at that time, and determines whether or not modeling (formation of the modeled object 115) is completed. Step S307 is repeated until the completion of modeling is confirmed.
After the modeling is completed, the process proceeds to step S309, and the temperature control unit 214 performs temperature control based on the set value for peeling related to the modeling material read in step S301. When the target temperature is reached, the control unit 203 notifies the UI unit 209 that it can be peeled off, and the shaped object 115 is peeled from the stage 114 in step S310.
Although not shown in FIG. 3, the modeling object 115 remains on the stage 114 when the modeling is stopped or when a new modeling object is formed at the time of starting the three-dimensional modeling apparatus ( May remain). Even in such a case, since it is necessary to peel the modeled object 115 from the stage 114, the same control as described above is performed.

As described above, in this embodiment, before the peeling operation for peeling the model 115 from the stage 114 is performed, an operation for assisting (supporting, facilitating) the peeling operation is performed. As this auxiliary operation, in this embodiment, in particular, the temperature control of the heater 116 is performed by the temperature control unit 214 so that the temperature near the stage surface 114a becomes the target temperature.
Thereby, since the contact part with the stage 114 of the modeling object 115 can be softened, it becomes possible to make it easy to peel the modeling object 115 from on the stage 114. FIG. Note that the vicinity of the stage surface 114a includes the stage surface 114a.

Here, in this embodiment, an example is shown in which the heater 116 that performs temperature control for assisting the peeling operation is incorporated in the stage 114, but the present invention is not limited to this, and the heater 116 is disposed in a place other than the stage 114. It may be a thing. The heater may be any means that can soften the contact portion of the modeled object 115 with the stage 114.
Further, the method for assisting the peeling operation for peeling the modeled object 115 from the stage 114 is not limited to the above method, and for example, a fluid (liquid and / or gas) is output between the stage 114 and the modeled object 115. (Discharge, discharge) may be used. Moreover, the thing which vibrates the stage 114 may be sufficient, and the modeling thing 115 may be immersed in warm water and stirred. In that case, after moving the modeling object 115 with the stage 114 from the 1st position at the time of modeling to the 2nd position different from a 1st position, you may peel the modeling object 115 from the stage 114. FIG. For example, after moving the modeling object 115 to the cleaning tank together with the stage 114, it may be stirred in warm water. These peeling methods can be combined as much as possible.

  Hereinafter, another embodiment relating to the peeling assist operation will be described. In the embodiment described below, different components from those in the first embodiment will be described, and the description of the same components as those in the first embodiment will be omitted.

[Example 2]
In the present embodiment, with respect to the configuration of the first embodiment described above, at least one layer of support material is laid (arranged) on the contact surface between the modeled object 115 and the stage 114. In the present invention and this specification, it is assumed that the entire object arranged on the stage is regarded as a modeled object, and when the support material is arranged between the modeled object 115 and the stage in this way, the support material is also a modeled object. Is considered part of If there are fewer types of support materials than the types of materials that make up the object that is actually desired, the heater can be controlled more easily than when no support materials are arranged as in the first embodiment. In addition, if a support material that can be easily peeled off from the stage is used, it is easier to peel off the modeled object. In addition, even if a part or all of the support material adheres to the stage, it does not affect the object, so that the possibility of damaging the object itself at the time of peeling is reduced.
In addition, about the support material arrange | positioned on a contact surface, you may perform the removal process similar to another support material, and you may perform a special removal process only about the support material of a contact surface. For example, the support material included in the shaped article 115 may be removed in a cleaning tank, and the support material on the contact surface may be removed on the stage.

[Example 3]
In step S309 in FIG. 3 of the first embodiment described above, the heater 116 is used when performing temperature control for peeling.
On the other hand, in this embodiment, a cooling unit is provided instead of the heater 116.
With such a configuration, when peeling is performed, the vicinity of the contact portion of the modeled object 115 with the stage 114 is cooled and temperature control is performed, so that peeling can be facilitated.

[Example 4]
In step S309 in FIG. 3 of the first embodiment described above, the heater 116 and the temperature control unit 214 are used to perform peeling.
On the other hand, in this embodiment, instead of the heater 116 and the temperature control unit 214, a liquid discharge unit built in the stage 114 and a liquid discharge control unit constituting the print engine unit 204 are provided.
With such a configuration, at the time of peeling, by discharging liquid near the contact portion of the modeled object 115 with the stage, at least a part of the contact part of the modeled object 115 with the stage is dissolved in the liquid, and peeling is performed. Can be made easier.

In that case, depending on the type of the structural material and the support material, the type of liquid suitable for peeling (to soften the contact portion of the model 115 with the stage 114) and the amount of liquid used in one peeling Is different. In this example, the type of liquid suitable for peeling and the amount of liquid used in a single peeling were set as set values.
Therefore, the setting values for modeling and peeling according to the cartridge transmitted from the cartridge detection unit 213 to the liquid ejection control unit are as shown in FIG.
FIG. 6 is a diagram illustrating an example of setting values for modeling and peeling according to the cartridge.
As shown in FIG. 4, the set value is set in advance for each cartridge, that is, according to the type of the modeling material. For example, when the cartridge ID is 0, the heater 113 is controlled to be XXX (° C.) during modeling, but at the time of peeling, the liquid A is controlled to be discharged a (ml).
Here, in the present embodiment, the type and amount of liquid ejected from the liquid ejection unit at the time of peeling are set according to the cartridge, but the present invention is not limited to this. In other words, the type and / or amount of liquid ejected from the liquid ejection unit at the time of peeling may be set in advance for each cartridge.

[Example 5]
In step S309 in FIG. 3 of the first embodiment described above, the heater 116 and the temperature control unit 214 are used to perform peeling.
In contrast, in this embodiment, instead of the heater 116 and the temperature control unit 214, a gas discharge unit built in the stage 114 and a gas discharge control unit constituting the print engine unit 204 are provided.
With such a configuration, when peeling is performed, the gas can be easily released by discharging a gas in the vicinity of a contact portion between the model 115 and the stage 114.

In that case, depending on the type of the structural material and the support material, the type of gas suitable for peeling (to soften the contact portion of the model 115 with the stage 114) and the amount of gas used in one peeling Is different. In this example, the type of gas suitable for stripping and the amount of gas used in one stripping were set as set values.
Therefore, the setting values for modeling and peeling according to the cartridge that the cartridge detection unit 213 transmits to the gas ejection control unit are as shown in FIG.
FIG. 7 is a diagram illustrating an example of setting values for modeling and peeling according to the cartridge. As illustrated in FIG. 7, the setting values are set in advance for each cartridge, that is, according to the type of the modeling material. Has been. For example, when the cartridge ID is 0, the heater 113 is controlled to be XXX (° C.) during modeling, but the gas C is controlled to be discharged c (ml) from the gas discharge portion at the time of peeling.
Here, in the present embodiment, the type and amount of gas discharged from the gas discharge portion at the time of peeling are set according to the cartridge, but the present invention is not limited to this. That is, the type and / or amount of gas discharged from the gas discharge unit at the time of peeling may be set in advance for each cartridge.

[Example 6]
In step S309 in FIG. 3 of the first embodiment described above, the heater 116 and the temperature control unit 214 are used to perform peeling.
In contrast, in this embodiment, instead of the heater 116 and the temperature control unit 214, a vibration unit built in the stage 114 and a vibration control unit constituting the print engine unit 204 are provided.
With such a configuration, when peeling is performed, the stage 114 can be vibrated to facilitate peeling.

In that case, depending on the type of the structural material and the support material, the bonding method between the stage 114 and the modeled object 115 is different, so the vibration frequency suitable for peeling and the vibration time in one peeling are different. In this example, the vibration frequency suitable for peeling and the vibration time for one peeling were set as the set values.
Therefore, the setting values for modeling and peeling according to the cartridge that the cartridge detection unit 213 transmits to the vibration control unit are as shown in FIG.
FIG. 8 is a diagram illustrating an example of setting values for modeling and peeling according to the cartridge in the present embodiment. As illustrated in FIG. 8, for each cartridge, that is, according to the type of the modeling material, A set value is set in advance. For example, when the cartridge ID is 0, the heater 113 is controlled to be XXX (° C.) during modeling, but the vibration unit is controlled to vibrate GGG (ms) at EEE (Hz) during peeling.
Here, in this embodiment, the frequency and time for vibrating the stage 114 are set according to the cartridge at the time of peeling, but the present invention is not limited to this. That is, the frequency and / or time for vibrating the stage 114 at the time of peeling may be set in advance for each cartridge.

[Example 7]
In Example 1 mentioned above, as a method of modeling the colored modeling object 115, the method of mixing colored particles with a structural material is employable. However, depending on the type of the colored particles, a difference occurs in the viscoelastic properties depending on the temperature, so that fine temperature control is required for each type of the colored particles.
Examples of a method for performing fine temperature control for each type of colored particles include a method in which heater groups are installed on the stage 114 in a grid shape, and the grid heater groups are individually controlled. In this case, when the processing of FIG. 3 is performed by the control unit 203, in step S309, the control unit 203 notifies the temperature control unit 214 of arrangement information of the modeling material that constitutes the modeling object 115 at the interface of the stage 114. To do. The temperature control unit 214 performs temperature control based on the arrangement information of the modeling material and the setting value for peeling related to the modeling material read in step S301. Then, when the target temperature is reached, the control unit 203 notifies the UI unit 209 that separation is possible, and the modeled object 115 is separated from the stage 114 in step S310.
